Cyanoacrylate adhesive

…an industrial cyanoacrylate adhesive withstood an 8,1-ton forklift for an hour. Thus, a new world record was set for the largest mass lifted by glue. During the record setting, the car was suspended from a crane on a steel cylinder with a diameter of only 7 cm. The two parts of the cylinder were glued together with 3M? Scotch Weld? Instant adhesive for plastic and rubber PR100. The forklift was lifted by engineers Jens Schoene and Dr. Markus Schleser of the RWTH University Aachen and featured on the German TV program Terra Xpress. A judge present at Guinness World Records watched the test for an hour before officially confirming the new record. Did the German team need to break the previous record to be successful? we managed to surpass him by as much as 90 kg. While the new world record demonstrates remarkable product performance in extremely harsh environments, industrial cyanoacrylate adhesives are equally effective in both everyday work and home use. A few drops are enough to get a strong bond of many metals, plastics and rubber. These fast-acting adhesives bond hundreds of material combinations in five to ten seconds, with 80% of full strength achieved within an hour.

Cyanoacrylate adhesives are single-component, fast setting methyl, ethyl and alkoxy based adhesives. They are designed to connect different pairs of materials (rubber, metal, wood, ceramics, plastics and materials that are difficult to bond, such as Teflon, polyolefins). Do they have different textures? from thin liquids to thick or jelly-like masses. They are used for very small gaps, up to a maximum of 0,15 mm. Cyanoacrylate adhesives polymerize due to the catalytic action of atmospheric humidity and are characterized by a very short reaction time. That is why they are sometimes called used adhesives. The temperature resistance of most types is from 55°C to +95°C (with the addition of a suitable stabilizer, strength up to +140°C can be obtained). Cyanoacrylate adhesives provide a strong bond on: steel, aluminum, plastics (e.g. PMMA, ABS, polystyrene, PVC , hard, and after applying a special primer even difficult-to-bond plastics such as polyethylene - PE and polypropylene - PP), elastomers (NBR, butyl, EPDM, SBR), leather, wood. Do these adhesives achieve shear strength? about 7 to 20 N/mm2. The strength depends on the material to be bonded, the fit of the parts (joint), temperature and type of adhesive. The disadvantage of these adhesives is sometimes a strong smell? especially noticeable at low humidity. Currently, manufacturers are developing more and more new generations of adhesives that allow you to connect low-adhering elements, with large gaps, odorless systems, and also do not cause sagging ("smoke") on adhesive joints. The joints are resistant to oils and fuels, to a lesser extent to moisture, especially at elevated temperatures. However, do they hold an important place in the industry due to the ease of execution and the speed of building strength in the hands? for a few, a few tens of seconds.
